SPECIFICATION forming part of Letters Application filed August 18, 1880.

To all whom it may concern Be it known that I, RICHARD BUSH, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Pumps; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification, and in whichii Figure 1 is a side, and Fig. 2 a detail, view of the device. it

My invention consists in closing the {discharge-pipe by means of a tompion or plug, or its equivalent, and exhausting the air in pipe and pump through opening in tompion or in pipe; also, in the use, at end of induction, of the perforated suction-pipe.

The object of my invention is, first, to provide a means of charging a centrifugal pump without the use of a foot or other valve in pump or pipe second, to provide a means whereby the choking or overloading of suction-pipe is prevented when pumping coal or other foreign or weighty substances.

In pumping sand, coal, stones, 850., it has always been found difficult to prevent the choking or overloading of the suction-pipe with sand, coal, 850., by reason of a lack of sufficient water to carry the same through pipes and pump. This choking I prevent by the use of holes near the end of suction-pipe,

Patent No. 232,935, dated October 5, 1880.

which admit a supply of water to aid in carrying through the pipe the material entering at the end of said pipe.

In the accompanying drawings, A is the tompion or plug through which, at G, connection is made between interior of dischargepipe and exhauster B.

D is the discharge-pipe. G is a centrifugal pump. E is the suction-pipe, to which is at tached end piece, H, which has bottom end open, and is perforated at F.

In case the bottom opening'of the suctionsection becomes clogged by coal or other substances the water can pass through the perforations, and the pump will not, therefore, cease operating.

Having thus described my invention, I claim 1. In combination with adischargepipe of a centrifugal pump and the suction-pipe of an air-pump, the plug G, whereby the centrifugal pump can be primed, substantially as described.

2. In combination with a centrifugal pump, the SL1CllOI1-1)lC6 having an open bottom and holes in the side, whereby a free flow of water is allowed, and'choking by coal or other substances prevented, substantially as described.

IVitness my hand this 6th day of August, 1880.

RICHARD BUSH.
